I just did Trans America Trail (~12000mi total) on converted to tubeless with 3M tape rims and while I didn't run superlow pressures there weren't any noticeable difference in 20-40psi range. They were superb even when plug blew at 70mph on rear Mitas E-07 the tire didn't come off. The MotoZ Tractionator RallZ and GPS which replaced Mitas halfway didn't behave any different. If anything they ran cooler at highway speeds.
The tubes make tire somewhat stiffer so if you run exactly the same tire to get the same feeling you need +2-3psi. Beware that MotoZ tubed and tubeless tires are different; not only that tubeless have stiffer sidewalls but in 21" front they're designed for wider rims. IIRC 21" tubed requires 1.85" and tubeless 2.15" wide rim good luck.
